Chinese patent CN202986652U discloses a kind of hub of motorcycle, and as shown in Figure 1, it has five spokes, and two triangles of top to top that described spoke is formed by the first reinforced rib and the second reinforced rib are formed, and described reinforced rib is bending shape.The complex structure of above-mentioned wheel hub spoke, the interface point of spoke structure stress is many, easily produces casting stress, and casting difficulty is large.Therefore, in view of the defect existed in prior art is improved.
Summary of the invention:
Object of the present invention is exactly the deficiency for prior art, and provides the two spoke barrel of a kind of Motorcycle Aluminum Alloy of totally-enclosed hollow and manufacture method thereof, has simple and reasonable, that mould is succinct, convenient and practical advantage.
Technology solution of the present invention is as follows:
A kind of two spoke barrel of Motorcycle Aluminum Alloy of totally-enclosed hollow, comprise tympanic part, spoke, wheel rim, the initiating terminal of described spoke is connected with tympanic part, tail end is connected with wheel rim, described wheel hub is provided with two spokes, the initiating terminal of described spoke be arranged on tympanic part circumferentially and the setting of 180 °, interval, described spoke is hollow structure, two sides of spoke are symmetrically arranged with two groups of knock holees, described knock hole distributes along the length bearing of trend of spoke, described knock hole internal fixtion is provided with rivet, the end face of described rivet and the flush with outer surface of spoke.
Preferred as technique scheme, described spoke is provided with altogether four knock holees, described knock hole is one group between two and is arranged on spoke two side in opposite directions.
Preferred as technique scheme, the diameter of described knock hole is preferably 10 ~ 12mm.
Preferred as technique scheme, the wall thickness of described spoke is preferably 4 ~ 5mm.
Preferred as technique scheme, the shape of described spoke is in " comma " shape.
Preferred as technique scheme, described rivet and knock hole interference fit.
Preferred as technique scheme, described rivet the selection of material is aluminum.
A manufacture method for the two spoke barrel of Motorcycle Aluminum Alloy of totally-enclosed hollow, comprises the following steps,
A) hub mold processed and core mold is opened respectively;
B) casting wheel hub blank;
C) stub bar, rising head and the burr on wheel hub blank is removed;
D) Quenching Treatment is carried out to wheel hub;
E) wheel hub after quenching is corrected shape and ageing treatment;
F) block knock hole with rivet, by the end face of rivet polishing to spoke flush with outer surface;
G) ball blast, machinework, external coating process are carried out to wheel hub.
Beneficial effect of the present invention is: wheel hub of the present invention is only provided with two spokes, break the routine that more than three or three spokes are set, and the shape of spoke is in " comma " shape, structure is simple, the mould that spoke relates to is more more succinct than the mould of existing product, more concentrated, becomes two spoke runners by some traditional spoke runners, make the flowing power of aluminium water better, be more conducive to the shaping of gravitational casting; The uniform wall thickness of described spoke, and the structure of arc transition, avoid in the past in structure unnecessary casting stress concentrate the problem with structural stress interface point, wheel hub intensity is not weakened because reducing spoke quantity.
In addition, described spoke adopts totally-enclosed hollow structure, the core suspended is adopted during making, by the knock hole location on spoke, after completing, after utilizing aluminium matter rivet to fill described knock hole, then rivet end face is polished smooth, make itself and spoke flush with outer surface, thus reach fully enclosed effect; The totally-enclosed hollow structure of described spoke is while lightweight wheel hub, stopping the foreign material such as rainwater, stone, earth, branch in motorcycle driving process enters in the cavity of spoke, causes abnormal sound, turn avoid wind and be blown into cavity, avoid increase windage, convenient and practical.
